Proximity Beacon, app integration and pushing to external webserver

We’re looking to develop a proof of concept which will untilise an app we already have developed.

We were looking to purchase the proximity beacons and when the user was within range and the app detects this we’d want to trigger a push from the app to a webserver to update a count or info about the person.

Is this possible with these beacons?

Yes, the Proximity Beacons and Proximity SDK should work perfectly fine for this:

Your app will get an enter event from our SDK when the user comes in range of the beacon(s), and then you can handle it however you like, including a request to a web server.
